Timeline Group Height

[ilusha]

I've started a new thread becouse that question can be interested to others members of the comunity. The exThread is: 
http://www.telerik.com/forums/timeline-group-sorting
Now my question about group height of groups in timeline control.
I have 3 groups (pic1) and i've got TimelineGroupPeriodControl instances (MainTimeline is my instance of radtimeline):

                var e = MainTimeline.ChildrenOfType<TimelineGroupPeriodControl>().ToList();
                e.ForEach(control =>
                {
                    var str = control.ActualHeight.ToString(CultureInfo.InvariantCulture);
                    builder.AppendLine(str);
                });
                MessageBox.Show(builder.ToString());

When the control is in state such as pic1 this code returns me result: 15, 15, 15;
When the items intersecs such as pic2 this code return me 15, 15, 15 too.
But the actual height of period groups is differnt in this 2 cases. How can I get the actualHeight of group. And groupName (скл... in my case) too.
Thanks!
nd one more qustion. With the new version of teleik wpf cotrols (2014) the radtimeline throws an exception in XAML visual designer. The stack trace is:

XamlParseException: TargetType "RadSlider" is not match the type of element "TimelineScrollBar".

Hello,

I am afraid I have misled you. The name of the class that represents the groups of items is TimelineItemGroupControl. That is why, your code should look like the following code snippet:

var groups = this.RadTimeline1.ChildrenOfType<TimelineItemGroupControl>().ToList();

StringBuilder builder = new StringBuilder();

foreach (var group in groups)
{
    var str = group.ActualHeight.ToString(CultureInfo.InvariantCulture);
    builder.AppendLine(str);
}

MessageBox.Show(builder.ToString());

Regarding the design-time exception - unfortunately, I was not able to reproduce it. In case the problem persists, please open a new support ticket and send me a simple running project, demonstrating the problem.
